The world wide data of slip distribution on the rupture plane of 211 earthquakes are collected from the Finite-Source Rupture Model Database on eQuake-RC web site and other data sources. Values of local parameters, mainly on asperity, are acquired from each slip diagram. Scaling laws of the parameters, such as area, length, average slip of the maximum asperity and the other asperity, local coordinates of the asperity center and the rupture starting point, are developed respectively for three rupture types and two kinds of seismo-tectonic characteristics, intraplate and subduction zone. Based on our contrastive analysis, we find that the discreteness and relative error of the relationship between asperity parameters and the corresponding global parameters is much smaller than those between asperity parameters and moment magnitude, and compared with those from references, which shows that our study improves the reliability of scaling laws of local parameters in the finite-fault model due to the amount of data greatly increased.
